To all whom it may concern:

Be it known thatl, CHANNING/hi. THOMP- at Newark, in the .county of Licking an State ofOhio, have invented a new and useful Hose-Clamp, of which the following is a specification. 1

This invention relates to hose-clamps of the type described and claimed in my United States ap lication, Serial No. 293,501., filed December 2-7, 1905.

The objects ofthe present invention are to ing means for the inner ends of the arcuate membersof'the clamp and-to rovide improved means forezgerting a we ging action on the hose at the outefineetingends of said arcuate members. j

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and int-he details of construction hereinafter described and claimed, it being understood that I do not desire to be limited to the particular arrangement shown in the drawing, as changes claims without departing from the spirit of" the invention or sacrificing any of its'advann the accompanying drawings, forming a part of this specification, Figure 1 is a transconstructed in accordance with my invention. Fig. 2 is a perspective view of the improved clamp.

Like reference numerals indicate corresponding parts in the diflerent figures of the drawing.

' The improved hose-clamp of this invention members A and B, the member B preferably being longer than the member A, so as to em- The member B, which I shall term the long member, is formed, preferably, with a pair of longitudinal slots 1 and 2, which are sepawhich serves to connect the portions of the member B on opposite sides of the longitudinal slots 1 and 2. The slot-s 1 and 2 preferably extend practica'zlly the entire lengthof the member B, so as to render the-same more flexible than if it were solid and to decrease the amount of material necessary to be used. '1

tachably together.

The improved means which I have ro -4 vided for detachably securing the mem ers Aand B together comprises a pair of hooks '4, which are formed integral with what I shall term the inner end of the member B and are located on opposite sides of the open- -ended slot 2. .As shown clearly in the drawing, the hooks ,4 are disposed practically at a right angle to the adjacent portion of the member Bend are slightly bent. This form of the hooks 4 constitutes an improvement over the hooks shown in my before-mentiond application,- which are bent backwardly into parallelism with. the adjacent portion of the member B,,for'the3reason'that the hooks herein shown require less material and are ;more readily engaged by the other member of the clam former application. The member A is formed witha shank 5, which is gradually decreased in width or tapered,"so that its inner end 6 is'of a width equal to the distance between the hooks 40f the-member B-that is, the width of the portion 6 is about the t Y same as the Width of the slot 2 in the member B. The inner end 6 of the shank 5 is bent slightly outward, as shown, and is formed with an enlarged head 7, which extends be yond the, end of theshank 5, as shown, and is oflset outwardly therefrom by reason of .theslight bend at 6.. Then the small end of the shank 5 is fitted between the hooks 4, the head 7 rests against the outer ortion of the than are the hooks in my member 13, said head 7 being ormed with a' I pair of shoulders 8, which test in engagement with the right-angular hooks 4 and serve to hold the two members A and B de- The pur ose in view in bending the sh nk 5 slighty outward, as shown at 6, is t at it isidesirable that the shank" 5 shall form a continuation of the are or circle of the member B and that the head 7 shall be located beyond the end of the shank 5 and slightly ofi'set' inan outward direction therefrom, so that it will not be 'necesary for the shank 5 to extend any distance into the slot 2. The arrangement of the slightly-curved hooks 4 at a right angle to the adjacent portion of the member B and the head located beyond and slightly ofiset from the shank 5 constitutes a simple and improved means of detachably securingto At its outer end the member B is formed with an outwardly or radially extending ear 10, having an elongated perforation-11 and the member, A is formed with a similar ear 12, having. an elongated perforation or slot 13 and a rearwardly-bent flange 14, the-slot 13 being formed,preferably, :by stamping out an integral wedge-shaped tongue 15, which forms a continuation of the arc of the'ihemand B, although I can, of course, use other equivalent means for accomplishing this result whenever required.

..A further improvement of my present inirention over my former construction. consists in extending the slot 1 in. the member B entirely to the outer end of said member, asindicated at 18, said outer end 18 of the slot 1 being partially closed by a shoulder 19, formed on the ear 10. When the outer ends fthe members A and B are drawn'together by the bolt 16, the forward end of the wedgeshaped tongue 15 enters the outer end of the slot 1 and slides along the shoulder 19, which partially closes said slot, the action of the shoulder being to cause the wedge-shaped tongue 15 to be forced hard down upon the same securely and produce a portion of the circle formed bythe members A and B. By

extending the slot 1 in the manner described and by slightly closing the end thereof by the shoulder 1.9 it is possible -to use a wedgeshaped tongue which is strong-inconstruction and which is prevented by the slot 1 from becoming laterally. bent or displaced after it enters and is guided forward in the slot 1.

The hose-clamp of this invention is strong,

durable, and inexpensive in construction, as well as thoroughlyefiicient in operation.

-' What is claimed is I v -'1. A hose-clamp comprising a pair of arouate members one member having a lu and a longitudinal slot terminating-at the" "'e of the lug, the othermemberbeing provided with a lug having a tongue stamped out therefrom and sha ed to engagein the slot and under the lu o the first member, a bolt extending throng the lugs of the members for drawing them together, ,and means on the members for connecting them together by a relative lateral movement at the ends opposite those having the. lugs, said means eompfrising radially-extending spaced hooks ran-one member, a head on the other member 'engag'ing under the hooks, and a portion ad jacent the head ext-ending'between the hooks.

2. A hose-clamp comprising a pair of arouate members, one havingloutwardly-projecting hooks and theother' aving a shank bent slightly outward to fit between the hooks, and ahead extending beyond the shank and engaging the hooks.

A hose-clampcomprising a pair of arcuate members, one member having a lug and a longitudinal slot terminating at the base of the 'lug, the other member being provided with a lug havinga tongue stamped out t-herefrom and shaped-to engage in the slot and under the lug of the first member, and means extending through the lugs of the members for drawing the latter together.

4. A hose-clamp comprising a pair of arouate members, one having a plurality of slightlybent hooks arranged approximately periphery-of the hose, so as to clamp. the i at a right angle to the adja ent portion of the member, and the other having a shank and a head extending beyond and oilset outwardly from the shank to engage the hooks.

In testimony that I claim the foregoing as my own I have hereto ai'lixed my signature in the presence of two witnesses.
